I ..lirus S. EMERY, of. Philadelphia, State of Pennsylvania, have invented a Mach ne for Making Press-Bricks, of which the following IS a specification.

Nature and Objeotof the Invention. The object of my invention is to render automatic the hand-presses which are-incommon use for'manufactoring press bricks; and

My invention consist's principally in arranging a number of such presses radially upon a horizontal disk or plate, to which an intermittent rotary motion is imparted, the several parts of each press being ope cratcd automatically, as the disk'rotates, in a manner which w ll be fully described-hereafter. I

Description of the dcconnmnpinp Draining;

. Figure 1, sheet 1, is a verticalsectionalview ofliny 'thc bed-plate,

General Description, The frame of the machine consists, in thepresent instance, of-a bed-plate, A, of uprights and side bmccsB, secured to the same and connected together by cross-pieces, and of a; horizontal frame, 0, attached to the uprights, andarran'ged to'support the upper.

' portion'ot' the machine. 'f

The vertical driving-shaft D turns in suitable bear ings in the frame 0, and is furnished with a drivingpulley, a, and with a toothed pinion, b, which gears into a. cog-wheel, b, of avertical spindle, E, the latframe 0. r

The lower end of the driving-shatt'l) is reduced in diameter, and extends downward into a clay-tempering hopper or mill, F, which is suspended from the bottom of the frame 0, the shaft within the hopper ter also turning in bearings provided for it on the.

being provided with agitators or knives c and with a forcing-screw, 0, but, as this portion of the machine forms no part of mypresc'nt invention, it can be altered or'modificd to any desired extent.

The spindle E is furnished, at a point beneath its l cog-whcel b', with an adjustable arm, (I, (figs. 1' and 4,) which is arranged at ,each revolution of the spin i die to strike one ofa number of pins (1', which project from the upperface of a disk, G, secured'to the top Philadelphia, counti V of of a vertical shaft, H, the latter having its bearings in the step e of thebed-plate, and in the frame at t a point beneath the disk G.

Thepins d are, in the present instance, six in num her, and are arranged in a. circle upon the disk G: so that they may be struck and turned successively by the arm at, the said disk and shaft H making, oonse-' quently, but one revolution for every six revolutions of the spindle E. i

I is a'hoiizontal disk or circular plate, secured to the shaft H in any suitable manner, and arranged to support a number of separate and independent brickpresses JJ J, &c., which are suspended beneath the said disk, so that they niaytnrn with the same and 'ivith the shaft H, as will be readily-understood on reference to figs. 1,2, and 3. j I

These presses are arranged radially upon the disk I close to the periphery of the same, and at regular distances apart from each other, they being, in' the presentinstance,'six -in number, to correspond with the number of pins d, and dividing the surface of the diskinto six equal sections.

These presses, it should be understood, are pre vcisely similar to those in common use for making press-bricks by hand, the main-objectof my invention-being to render such presses automatic in their action; but, in order to fully understand the operation of the complete machine, it will be necessary to describe the" construction of the presses, views of which, drawn to an enlargedscale, are shown in. figs. 7 and 8.- p

Each press consists of firmly secured to the disk I, and connected together at the bottom by a bar, c'.- l

t A mold, f, of the same length and width as .the

brick whichis to-be made, isformed in 'the outer rim f of the disk I, at a point between the side frames '0 e ofeach of the presses, these molds, as the disk is rotated, beiug brought one ata time beneath the opposite 'side'frames e e,

lower open end of the hopper F,to receive their charge of clay, as will be hereafter described.

A vertical dieor plunger, g, is arranged to slide in each mold f, the lower end of this plunger (fur nished with a suitable anti-friction roller) being supported by the short armof a lever, h, which, under the circumstances described hereafter, rests upon the bar 0'." I

The lever It has its fulcrum in a -pin, it, which projects through, and is arranged to slide vertically in slots formed in the opposite side framese e, and

the long arm of the said'lever'is connected bye-link,

i, to an arm,i, ot a rock-spindle, j, which turns in the side frames e e. I i

The plunger g, besides being operated'by the" levcr It, is also acted on by an arm, k, hung to the dle j are so turned by meansof a rod, 1, furnished at its outer end with a roller, T, which traverses a stationary cam, r of the bed-plate, that both the plunger and cap 1) may be drawu 'simultaiieously,-or nearly so, toward each other, to impart the' required pressure to thebrick. I

The automatic throwing back of y the cap 12 from the mold, after the brick ha'sbcen pressed, is efiected by a rod, 8, secured to the cap, and arranged to strikeand to be turned by a camlike plate, 3', secured to 'the frame O. r

The, rod 3 also serves'as a medium. for pushing the cap forward over the mold, after the latter has been filled with clay, it-being'operated at the .pro-' per moment by a' swinging arm, t, under the -con-.

trol of a bell-crank lever, .t, which is maintained in such a position by a spring, t, that itmay be struck and turned by a pin, a, on the 'under side o f the cog-wheel b.

H Operation.

Motion having been imparted to the driving-shaft, is transmitted, through the, gearing described, to the shalt H and disk I, the intermittent motion in the direction of the arrow, which is thus imparted to the latter, permitting each of the presses to remain directly beneath the mill F for a sufiicient time to enable its mold to be completely filled with clay, the

latter beingyeit-her-dry or tempered, according to circumstances. I

As soon as the mold'of on'eof the presses has been filled, the 'disk I, by the action of the arm (1 upon one of the pins (1, is moved :to the extent of one-sixth of a revolution, or until the next press is brought beneath the hopper.

During this partial movement of the disk the cap 1) of the first .press remains. thrownbaek 'for' a snflicint interval to enable the upper face of the brickin the mold to be dusted-with sand or loamby an attendant, but, during the last portion of the movement, the cap isthrown forward so as to coverthe mold, by means of its rod 3, which-is struck by the vibrating arm t, the latter being turned by the spring lever tkwhich is' operated by the pin "u of the cogwheel I), (see figs. 3 and .5.)

The first press has now reached the position indicated by. the number 2 in fig. 3,,and at the next partial revolution of the disk it' is moved to. the third position, the brick within the mold receiving, during this latter movement, the requisite degree of pressure between the-plunger g and cap p, as 'Lwill now proused to describe.

At the beginning of the third movement the roller r, at the outer end of the rodn', gradually ascends the incline 0", until the said rod assumes the elevated position shown in fig. 7. This will depress the long arm of the lever 71, and cause its short arm to be c'orrespondingly elevated, which movement, by exerting an'npward movement on the plunger 9, will cause a depression of the sliding fulcrum h, andaconseque'nt binding of the cap 11 upon the top of the mold-during said upward pressure of the plunger.

After the brick has been thus pressed in the mold, and before the completion of the third movement of the disk, the'rod'r descends the abrupt portion of the incline 'r, and again rests upon the bed-plate, this having rhe-efiect of lowen'ng the plunger g, and of slightly raising the cap 1) above the mold, so that it may bereadily thrown back from the same.

While the press is being movedfrom the third to the fourth position, the cap is thrown back from the mold by the camdike plate 8', with which the rod s of the said cap is brought in contact, the several parts of the press being now'in the position shownon the left-hand side of fi 1.

' During the next movement of the disk, and'while the'press is being brought to the fifth position, (figs 3,) the roller 1' of the arnrl traverses the incline m,

and thereby raises the said arm, the latter, through the medium of the rod hf and arm 7c, elevating the plunger 9 to its full extent, so as to raise the brick out of the mold.

The brick-is removedby an attendant, and another attendant wipes oil the mold, before the descent of the-plunger; or, as is to be preferred, this wiping can be efi'ected automatically.

During the sixth movement of the disk the arm 1 passes the-. lincline m, and is depressed so that the plunger g again descends to its former position, and before the'press again passes beneath the'hopper, to receive a second charge of clay, the interior of the mold should be dusted (either automatically or by an attendant) with loam or fine sand.

Each of the presses with which the disk is furnished is complete in itself, and is operated automatically in precisely the same manner as the first, the movements of the several parts of each press being conducted precisely as in the hand-machine, but with much greater rapidity and regularity. Although I'have described the disk as being adapted for six presses, any greater or less, number can be arranged upon the same, and it is not necessary that the bricks made by the several presses should be of the same size or shape, and two, three, or even a greater number of molds can, if desired, bearranged side by side in the same press.

The adjust-ability of the arm (1, by which the disk ,is driven, forms an important feature of my invention,

as, by lengthening or shortening the said arm, the point at which the disk will stop after each revolution can be regulated with the greatest nicety, this enabling-the effects of wear, &c., upon the machine to be readily overcome.

In some cases the intermediate cog-wheel b and its spindle E can be dispensed with, and power transmitted direct-1y from the driving-shaft to the shaft H.

It will be evident, without further description, that by arranging a number of the within-described presses upon a rotating disk, I, and thus rendering their movement entirely automatic, bricks fully equal to the hand-made article can be produced with great rapidity, and without requiring the skilled labor that is usually demanded in the manufacture .of pressed bricks.

It shouldbe understood, however, that I do not deshe to claim broadly a b ick-machine in which 'molds are formed in a'rotating disk, but merely the arrangement, upon a rotating'disk or plate, in sucha manner that they can be operated automatically, of the within described complete hand-presses, which have been -found in practice to be the best adapted for the production of press-bricks; therefore, instead of the camplate 8', pin u, arms t t, and inclines r and m, other well-known mechanical devices and movements, operating in. a like manner, maybe employed.
